{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci cation. SeeCapacities
and Specifications on page 5-114for wheel
nut torque speci cation.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly tighten
the wheel nuts in the proper sequence and to
the proper torque speci cation. SeeCapacities
and Specifications on page 5-114for the wheel
nut torque speci cation.9. Tighten the nuts rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
When you reinstall the regular wheel and tire, you must
also reinstall the either the center cap, or bolt-on hub
cap, depending on what your vehicle is equipped
with. For center caps, place the cap on the wheel
and tap it into place until it seats ush with the wheel.
The cap only goes on one way. Be sure to line up
the tab on the center cap with the indentation on the
wheel. For bolt-on hub caps, align the plastic nut caps
with the wheel nuts and then tighten by hand. Then
use the wheel wrench to tighten.
